用一种不规范的句子语序也是符合语法的。

“ why+不定式”时，不定式的动词常是不及物动词。

why don't是疑问的用法：Why don' t you an swer this ques tio n 为什么不回答这些
问题
because, since, as 和for引导的原因状语从句
1.because（因为）：表示直接的原因或理由，着重点在从句，用于回答why，语气最强。

He didn ' t go to school because he was ill.
Why didn' t he go to school
Because he was ill.
2.since（既然）：一般表示对方已知的，无须加以说明的既成事实的理由，全句中心在主句，语
气比because弱。

Si nee you are ill, I ' ll go alone.
3.as（由于）：表示十分明显的原因，一般说明因果关系，着重点在主句，语气较弱。

As it is snowing, we shall not go to the park.
4.for（因为，其理由是）：是个并列连词，只能放在另一个并列句后面，表示推理或解释，或用作附加说明，表示新的情况，而不是指理由或原因，语气最弱，一般不放在句首。

The day breaks, for the birds are singing.
* for表示因果关系时，可以同because交替使用，但for前须用逗号，而because则不必。

You couldn ' t have seen him because he wasn ' t there.
=You couldn ' t have seen him, for he wasn ' t there.
*当原因是显而易见的或已为人们所知，就用as或since，且多放在句首。

Since/ As the weather is so bad, we have to delay our journ ey.
女口：He is as strong as a horse. 他力大如牛。

as…as的基本用法
用于比较句型，中间插入的是形容词或副词的原级。

意思是“达到与什么相同的程度”
几个习惯用法：
1.as soon as
引导一个时间状语从句:
I ' ll call you as soon a s I finish my homework. 我一完成我的作业，就给你打电话。

2.as long as
She has searched the information about dinosaurs on the Internet as long as three hours.
她在因特网上搜索有关恐龙的信息已经长达三个小时。

3.as much as
Some of the stones weigh as much as fifteen tons. 有些石头重达15 吨。

The same as 的用法：
the same as :禾口..... 一样
例如：His dream is the same as mine. 他的梦想和我的一样。

the same to :一般用习语: The same to you! （在别人向自己祝福后，用这句话给别人同样的祝福）。

the same with :适合于 ......... 。

例如: My thought are also same with Mary. 我的想法对Mary 也适用。

different from 和different than 英语和美语中都经常见。

当直接对两人或两物进行比较时，from 是最保
险的选择: My book is different from （not than ） yours.
但different than 的比较对象用一完整的句子表示，特别是在美语用法中，这种用法更能接受:
The campus is different than it was 20 years ago.
校园和二十年前不一样了。

The campus is different from how it was 20 years ago.
校园和二十年前的样子不一样了。

（二）写作练习:如何解决环境污染问题

Director
Shan ghai Environment Bureau
Dear Sir/ Madam
I am writing to inform you about three problems that are causing damage to our en viro nment.
The first problem is an air problem. It occurs on Bird Street. It is caused by
a factory build ing. A lot of unpleasant smoke comes out of the building ' s chimney. Its effect is to pollute the area and make everythi ng smell un pleasa nt.
The sec nd problem is a no ise problem. It occurs all around our school. There
are too man years and lorries rush ing by. When there is a traffic jam, every one sounds their horn s. Its effect
is to make it difficult for us to study.
The third problem is a rubbish problem. It occurs on Sandfield Road. It is caused by people giving out
leaflets that are thrown on the pavement. Its effect is to make the area untidy and to waste a lot of paper.
I would be grateful if you could let meknow what you can do about these problems.
I hope that you will take action quickly before the environment is damaged too much.
Thank you.
Yours fa ithfully
